Tenneco Automotive Operating Company Inc. designs, engineers and manufactures exhaust system components aimed at improving fuel economy while reducing engine noise. Most exhaust components are made of stainless steels which provide excellent oxidation and corrosion resistance. The aim of this work is to investigate the feasibility of manufacturing exhaust components out of novel multi-layer steel. The outer layer of the multi-layer steel has a chromium content which is higher than that typically used for present exhaust applications. As a result, the new steel is expected to offer better corrosion and high temperature oxidation resistance compared to traditional stainless steels. In addition, the multi-layer steel is expected to have better ductility than existing stainless steels because the core layer is made of a very ductile substrate. The goals of this work are to: a) measure the forming limit diagram of the multi-layer in order to compare its formability to that of traditional stainless steels and b) compare the corrosion and high temperature oxidation behavior of the multi-layer steel to that of traditional stainless steels. Based on the initial findings the composition of the surface and core layers may be modified in order further improve the performance of the multi-layer steel. Actual size components, made from the new material, will be manufactured and tested by the end of the project. The project will train one undergraduate student, two Master's students and one Post Doctoral Fellow.x000D
